Collectible Card Game Headquarters

As I'm quite new to magic I find forges random deck generation to be quite cool. On question I have though, is there any way I can randomly create decks using only cards that I own for real?
I think this would be very helpful and fun.

Maybe you can create a cube with just the cards you own, but that would probably be pretty laborious.

Forge was written to give its author the ability to play with cards he didn't own, nor do most players.. like the Moxen or Black Lotus.

Creating a cube would only work for limited mode. I guess the Random deck generator could be adapted at some point to build from a cube.
